These things seem to be pretty common. There's the D. Bookish link above, the "benny lava" vid. (probably the funniest I've seen: thanks to SEK at Acephalous for it), the "Angel of Death" one (which is probably funniest for fans of the song), and portions of the Japanese Bewitched that appear on this issue of Wholphin.

Given that I've only learned what "Sweded" means (for example!) in the past month or so, this means there must be 100s of these subtitlings.
